Now the progress in caving gear, especially lighting, is a whole other thing.
Lugging carbide around. Having to find water.
Or those miners lamps that weighed a ton and had indifferent life.
My thing was photography - so a whole other load of kit to transport.
Those were the days.
Mmm, cave photography. I usually tried to avoid getting roped into cave photography trips, particularly in the old days before slave flashes when somebody would be lumbered with a bloomin' tripod to carry and then you'd freeze your bollocks off whilst the photographer faffed with all their kit. I've seen a couple of rebellions on photo trips, in particular on where I was the model chest deep in freezing water. "Another ten 30 seconds and that's yer lot !". I did do some half hearted attempts myself but nothing much. I remember seeking out an SLR which would fit in a small ammo can (on its back) with lens attached. The old Pentax MX was one of very few models that would do this but it was a lot better than lugging a great big .50 caliber ammo can which you needed for most cameras. The modern plastic drums are a lot less pain to carry.
As an aside a mate commented that he much preferred the old film photography for caving as you had a couple of weeks imagining they great shots you'd taken, before the disappointment when they got developed. With digital you'd see they were shoot straightaway so didn't even get the pleasure of anticipation.
Mind you, carrying someone's diving bottles is even less fun than a camera trip
